LOG LOADING AND SKIDDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 757,234, dated April12, 1904.

Application filed October 23, 1903- To all whom, it may concern:

Be it known that I, MICHAEL SoHMAL'rz, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Log Loading andSkidding Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to log loading and skidding machines.

It consists of an engine-bearing car, which Iwill call the locomotive orengine car, and of an exterior or envelop derrick car adapted to move onthe same track as the engine-car and when desired to suspend saidengine-car above said track.

It also consists of certain other constructions, combinations, andarrangements of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a machine embodying mysaid invention. Fig. 2 is a front end elevation of the same. Fig. 3 isan enlarged bottom plan view of one of the sills forming part of saidinvention. Fig. 4 is a still furtherenlarged crosssectional view of .thesame. Fig. 5 is a top plan view of said machine omitting the hoistingcables and showing the derrick poles partly broken away, and Fig. 6 is abottom plan view of said engine-car.

Referring to the drawings, the derrick-car consists, substantially, of aframe comprising transverse sills 1 and 2, brackets 3, mounted,respectively, upon the ends of each of said sills, posts 4 and 5,erected upon each of said brackets, transverse overhead beams 6 and 7 ateach end of said frame and secured in any suitable manner at their endsto the contiguous said posts, longitudinal upper beams8 at each side ofsaid frame, extending from the post 5 at one end of said frame to thesimilar post at the opposite end thereof and secured thereto by anysuitablemeans, as by brackets 9, longitudinal lower beams 10 at eachside of said frame, ex-

tending from the post 5 at one end of said frame to the similar post atthe opposite end Serial No. 178,184. (No model.)

thereof and secured thereto by any suitable means, as by brackets 11,derrick-poles 12,

pivotally connected at their lower ends to the opposite sides of saidframe, at one end thereof, and converging and secured together in anysuitable manner at their upper ends, as by a cap 13, and a spacing-post14, erected be tween each of said posts 4 and 5 and of lesser thicknessthan said posts 4 and 5, whereby vertical guideways are formed betweensaid posts 4 and 5. Said sills are preferably adapted to extend acrossthe rails A and B of a railway-track and are channeled underneath toreceive the shaft and wheels 16 of single supporting-trucks. Said sillsalso have formed thereon near each end hoods 17 to receive thejournal-boxes 18 of said trucks. Said trucks are preferably secured insaid sills by bolts 19, extending through said sills below the axles,but may be secured in any other suitable manner. Springs 20 arepreferably interposed between said boxes and the overhead portions ofsaid hoods, whereby said sills are normally raised clear of said trackand supported upon said trucks. When, however, the weight of theengine-car is suspended from the frame of said derrick-car, said boxesrecede in said hoods and said wheels recede in said sills and the sillsbear directly upon the track-rails. The sills 1 and 2 are also eachprovided near each of their ends with oppositely-directed angularextensions 21, the upper surfaces of which are inclined from the top ofsaid sill downwardly to said rails, and such inclined surfaces arepreferably formed with an offset portion 22 to accommodate the flangesof any wheels passing from said rails over said inclines. Between saidclevises 23 are preferably pivotally secured sockets 24, adapted toreceive the lower ends of said derrick-poles. Backstays 24 are securedin any suitable manner to the apex of said derrick and extenddivergently backward over rollers 25,1:nounted upon the upper part ofthe rear end of said frame and downwardly to windlasses 26, keyedto-similar transverse shafts 27 journaled in brackets-28, secured to therear end of said frame. Worm-wheels 29 are also keyed to each of saidshafts 27 and are adapted to engage Worms 30, keyed to shafts 31, whichare provided with a crankhandle 32 andjournaled in brackets 33, securedto the posts 4 and 5, respectively, at the rear corners of said frame,by means of which windlasses and backstays said derrick is adapted to beadjusted and held at any suitable angle. Mounted in any suitable manneron the transverse overhead beams or either one of them, at the front endof said machines, are antifriction-rollers 34, adapted to support saidbackstays when the outer end of the derrick is lowered below thehorizontal plane of said overhead beams. Suspended from the apex of saidderrick in any suitable or well-known manner is a hoisting-sheave 35,adapted to support a hoisting-cable 36. Pivotally secured in anysuitable manner to each of said sills or, preferably, as shown, to eachof said brackets are dogs or spuds 37, the free ends of which areadapted to drop down at an angle forwardly or rearwardly, as desired, toengage the ties to prevent the forward or rearward movement of saidderrick-car along said track. When not in use, said spuds may be swungupward and their free ends lodged in vertical guideways between saidcornerposts. It will be observed that said sills, with their inclinedextensions, form bridges over the trucks of the derrick-car, whichbridgesills have tracks formed upon them over which the engine-car orother cars may pass from the rails A and B. I therefore call said sillsbridge-sills. Said frame or derrick-car in most particulars correspondsin construction to the derrick-frame described in Letters Patent of theUnited States, dated May 12, 1903, No. 7 27 ,849, issued to me forlog-loading machine, and I do not now, therefore, claim the samebroadly.

The engine-car forming part of my said invention comprises aplatform-car 38 of any suitable construction, havinga hoisting,skidconstruction mounted thereon, the elements of said engine used forhoisting and those used for skidding being well known to the art and notnecessary to be particularly described herein. The shaft of one of thehoisting-drums of said engine is provided with a clutch 40, slidablykeyed thereto and adapted 'in operation to engage a sprocket-wheel 41,loosely journaled on said shaft. Said sprocketwheel is belted by a chain42 to a sprocketwheel 43, keyedto a shaft 44, journaled in bearings 45,depending from the frame of said car, beneath the platform thereof,which shaft 44 carries two other sprocket-wheels 46 and 47, keyedthereto and belted, respectively, to sprocket-wheels 48 and 49, keyed tothe axles of the forward and rearward trucks of said car, whereby saidengine is adapted to drive said car along the track. Said driving meansis substantially the same as shown in my said Patent No. 727,849. Theshaft of another of said drums is provided with a.

clutch 50, slidably keyed thereto and adapted in operation to engage asprocket-wheel 51, loosely journaled on said shaft and belted by a chain52 to a sprocket-wheel 53, keyed to a shaft 54, journaled in bearings55, depending from the frame of said car, beneath the platform thereof.Said shaft 54 also carries two other sprocket-Wheels 56 and 57, keyedthereto and respectively belted to sprocket-wheels 58 and 59, keyed toshafts 60 and 61, respectively, journaled, respectively, in bearings 62and 63, depending from the frame of said car, beneath the platformthereof. Said shaft 60 also carries a gear-wheel 64, keyed thereto andadapted to engage a gear-wheel 65, keyed to a shaft 66, journaled inbearings 67, depending from the frame of said car, beneath the platformthereof. The shaft 66 also carries two spools 68, keyed thereto. Theshaft 61 carries a gear-wheel 69, keyed thereto and adapted to engage agear-Wheel 7 O, keyed to. a shaft 71, which is journaled in bearings 72, depending from the frame of said car, beneath the platform thereof.Said shaft 71 also carries two spools 73, keyed thereto. Secured at oneend in any suitable manner to each of said spools are cables or chains74, extending therefrom upwardly through the platform of said car and inoperative position secured at their upper ends in any suitable manner tothe overhead portion of said derrick-frame. I preferably provide hooksupon the upper ends of said cables or chains adapted to engage the eyesof depending eyebolts 76, secured to plates 77, seated upon and boltedto said transverse beams 6 and 7. The chains are thus detachable attheir upper ends. It will now be readily understood that said enginecarmay be easily run from the track over the inclined extensions of eitherof the sills of said derrick-car and stopped between said sills and thatthe chains 74 may then be attached to said eyebolts 76 and theengine-car raised into suspension within and from said derrick-car, atwhich time empty logging-cars may be run through said derrick-carbeneath said enginecar. The engine-car may then be lowered and saidhoisting-cable 36 secured to one of the drums of said engine andoperated to lift logs onto the logging-car in front of said derrick.Said hoisting-cable may remain attached to said drum while saidengine-car is within the derrick-car whether the engine-car is raised orlowered. The engine-car may of course be easily disconnected from saidderrick-car and run out of the same. Skidding-lines may then be securedto one or more of said drums and operated to draw logs from a distanceto the track side, said skidding-lines being led in the usual andwell-known manner through guidepulleys or purchase-pulleys secured tostumps of trees or any suitable anchorage. When disconnected from saidderrick-car, said engine-car may also be used to push or pull othercarsor perform various other railway Services, to aid in whichcar-couplers 78 of any suitable construction are preferably secured tosaid engine-car, at each end thereof. In order to keep said engine-carfrom swaying while in suspension in said derrick-car and to preventlongitudinal movement of said enginecar with respect to saidderrick-car, I provide castings 79, secured in any suitable manner tosaid engine-car, at each corner thereof, upon each of which castings areformed upwardlydirected apertured lugs 80, adapted to receivehorizontally-arranged sliding bolts 81, projected therethrough andadapted in operation to loosely engage the guideways formed between thecontiguouscorner-posts of said derrick-car. Said bolts are furthersecured in operative position by pins 81, projected downwardly throughsaid bolts and into or through any suitable portion of said lugs orcastings.

When it is desired to disengage said engineciency for various purposes,possesses great advantages over other loading-machines and is especiallypractical for use on temporary railways and in localities Whereextensive repairing facilities are not conveniently at hand and wherewholly independent equipment for all the classes of service performableby said construction would be prohibitive. It will also be observed thatwhile loading the center of gravity of said machine is low and thetendency to tip over reduced to a minimum.

Having now described my invention, what I claim, and desire to secure byLetters Patent, 1s-
